Automatic Number Place Recognition Cameras otherwise known as ANPRs; are camera devices designed to work at certain wavelengths (dependent on Country) to read a license plate’s number of a vehicle to then track it through a database to identify any criminal offences links to that car, such as uninsured; stolen; major and organised crime; and even terrorism. They are typically installed on motorways; busy roads around cities and towns; and also on police cars as well as specialised ANPR police vans. Knight Optical offers Colour Glass Filters for such an application, be it either long pass or bandpass filters. The wavelengths typically used by ANPR camera companies are: 695nm; 740nm; 810nm; 850nm; 910nm and 940nm. We offer these filters as either long pass or band pass filters. We can also offer these as customised filters with specific band blocking coatings to optimise your wavelength of choice. For more details see PDF

Sapphire is an incredibly hard crystal (HK1370kg/mm2), second only to diamond. Fluoresence free sapphire windows have high mechanical strength, thermal and chemical resistance and is scratch resistant, making it very desirable for operating in harsh conditions. Sapphire windows can be made thinner than alternative crystals thanks to its structural integrity and can operate up to 2030⁰C. The material transmits between the UV and IR at 0.15-5.5µm, and has a high refractive index of 1.75.. Knight Optical supply a range of quality Sapphire optical components including Fluoresence free sapphire windows, Sapphire lenses, Sapphire prisms, and Sapphire blanks either from stock or bespoke custom made to your specification for a range of applications.  Our current range includes Random Polarization Sapphire that can be used for most applications apart from UV use.
